Rod in LaPorte, Indiana, has Welsh ancestry, and always wondered if the expressions to welsh on a bet suggests that the Welsh are dishonest. The verb to welsh and the noun welsher are indeed mild ethnic slurs. To welsh dates back to at least the 1850s, and because it may offend, should be replaced by other words such as renege, waffle, or flip-flop. Similarly, taffy, another old word for the Welsh, long carried similar connotations of being a habitual liar and cheater. This is part of a complete episode.
